当前的大容量光纤光栅传感技术,只针对管线损耗技术进行改进,忽略了高速数据传输的约束条件,导致光栅传感精度较差,提出一种高速数据传输环境下的大容量光纤光栅传感技术,通过高速数据传输环境、存储平台接收光纤通信系统技术数据包,采用MapReduce方法对存储的海量技术数据进行大范围汇总处理和分析,研究光纤光栅传感通信系统传输技术,获取光纤色散系数和管线损耗衰减系数,对限制光纤通信系统传输技术的光源啁啾、光源相位噪声、激光器偏置点以及消光比几种影响因素进行改进。实验结果表明,本文方法的传感精度高、耗能低,且能有效提升光纤传感通信系统传输性能。

The current high-capacity FBG sensing technology only improves the loss characteristics of pipelines,ignoring the constraints of high-speed data transmission,resulting in poor grating sensing accuracy.An improved method of large-capacity FBG sensing technology in high-speed data transmission environment is proposed.The characteristic data package of FBG communication system is received by large data analysis and storage platform.The massive characteristic data stored are collected,processed and analyzed by MapReduce method in a large range.The transmission characteristics of FBG sensing communication system are studied,and the dispersion coefficient and loss attenuation of pipeline are obtained.The factors that restrict the transmission characteristics of optical fiber communication system,such as chirp of light source,phase noise of light source,bias point of laser and extinction ratio,are improved.The experimental results show that the improved method has high sensing accuracy and low energy consumption,and can effectively improve the transmission performance of optical fiber sensing communication system.
